Seems the lincese is corrupted.
I recommend you the following:
-generate new license
-run md5sum against the license file on the machine where you generated the license. If you don't have md5sum for Windows, try ours: http://www.nusphere.com/sshot/md5sum.exe
-send the license to the server
-check md5sum of the license on the server and make sure it matces the original
